Multiple forms of cotyledonary b-galactosidases from Vigna unguiculata quiescent seeds

Cotyledonary b-galactosidases were isolated and partially purified from Pitiúba cowpea (Vigna unguiculata (L.) Walp.) quiescent seeds. The purification steps consisted of precipitation of the crude extract with ammonium sulphate in the range of 20-60% saturation, acid precipitation, DEAE-Sephadex ion-exchange chromatography and Lactosyl-Sepharose affinity chromatography. This purification process gave rise to three b-galactosidases-rich fractions: b-gal I, b-gal II and b-gal III, which were purified about 5, 509, and 62 fold, respectively. They reached maximal enzyme activity at different pH ranges: 3.5-4.5 for b-gal I, 3.0-3.5 for b-gal II, and 3.0-4.0 for b-gal III. Their maximal activities were reached when the temperature of the assay medium was 60° C, and preincubation of the enzymes at different temperatures has shown that they were heat-stable up to 50° C. There were no significant differences among the partially purified enzymes as far as their response to the different effectors tested, except for Mn2+ and EDTA, which affected differently b-gal I, b-gal II, and b-gal III. They were slightly affected by Mg2+, Ca2+, Zn2+, Co2+, tartarate, molybdate, glucose, and lactose, strongly inhibited by Cu2+ and galactose, and inactivated by Hg2+. These chemical and physical properties are similar to the ones found for other plant b-galactosidases. Although through this process of purification three isoforms of this enzyme were obtained, isoelectric focusing in polyacrylamide slab gel of these enzyme-proteins suggest that cotyledons of Pitiúba cowpea quiescent seeds possess four isoforms of b-galactosidases.

Oral tolerance induction with altered forms of ovalbumin

As a T cell-dependent phenomenon, oral tolerance is not expected to depend necessarily on native configuration of antigens. We investigated the induction of oral tolerance with modified ovalbumin (Ova). Oral administration of heat-denatured (HD-Ova) and cyanogen bromide-degraded ovalbumin was less effective than native Ova in inducing oral tolerance in B6D2F1 mice. HD-Ova was effective in suppressing delayed-type hypersensitivity (DTH) reactions but did not suppress specific antibody formation. Injection of Ova directly into the stomach, but not into the ileum or cecum, suppressed subsequent immunization to DTH reactions. Gavage with protease inhibitors (aprotinin or ovomucoid) before gavage with Ova was ineffective in blocking tolerance induction. Treatment with hydroxyurea to destroy cycling cells 24 h before gavage with Ova blocked oral tolerance induction and also the possibility to passively transfer tolerance to naive recipients with the serum of mice gavaged with Ova 1 h before. The implications of these findings about oral tolerance induction are discussed

Influence of exercise on the activity and the distribution between free and bound forms of glycolytic and associated enzymes in tissues of horse mackerel

The effects of short-term burst (5 min at 1.8 m/s) swimming and long-term cruiser (60 min at 1.2 m/s) swimming on maximal enzyme activities and enzyme distribution between free and bound states were assessed for nine glycolytic and associated enzymes in tissues of horse mackerel, Trachurus mediterraneus ponticus. The effects of exercise were greatest in white muscle. The activities of phosphofructokinase (PFK), pyruvate kinase (PK), fructose-1,6-bisphosphatase (FBPase), and phosphoglucomutase (PGM) all decreased to 47, 37, 37 and 67%, respectively, during 60-min exercise and all enzymes except phosphoglucoisomerase (PGI) and PGM showed a change in the extent of binding to subcellular particulate fractions during exercise. In red muscle, exercise affected the activities of PGI, FBPase, PFK, and lactate dehydrogenase (LDH) and altered percent binding of only PK and LDH. In liver, exercise increased the PK activity 2.3-fold and reduced PGI 1.7-fold only after 5 min of exercise but altered the percent binding of seven enzymes. Fewer effects were seen in brain, with changes in the activities of aldolase and PGM and in percent binding of hexokinase, PFK and PK. Changes in enzyme activities and in binding interactions with subcellular particulate matter appear to support the altered demands of tissue energy metabolism during exercise.

Circulating forms of parathyroid hormone detected with an immunofluorometric assay in patients with primary hyperparathyroidism and in hyperparathyroidism secondary to chronic renal failure

In patients with uremia, intact parathyroid hormone (PTH) measurement appears to overestimate the biologically active hormone in circulation. The recent description of the accumulation in these patients of a non-intact PTH form measured by the standard immunometric assays, re-opened the question. In this study we submitted serum samples from 7 patients with primary hyperparathyroidism (PHP) and from 10 patients with hyperparathyroidism secondary to chronic renal failure (SHP) to preparative HPLC in order to discriminate the molecular forms measured by our currently used immunofluorometric assay for intact PTH. The elution profile obtained with the HPLC system showed two clearly defined peaks, the first one corresponding to a lower molecular weight form, and the second to the intact PTH (1-84) form. In patients with SHP the area under the curve for the first peak (mean 29.5%, range 20.6 to 40.4%) was significantly greater than that observed for patients with PHP (mean 15.6%, range 5.6 to 21.9%). This confirms previous studies showing accumulation of molecular forms of slightly lower molecular weight, presumably PTH (7-84), in patients with SHP and, to a lesser extent, in patients with PHP. The real necessity of assays that discriminate between these two molecular forms is debatable.

MARKETING COMMUNICATIONS IN B2B COMPANIES – The Roles of Marketing Communication Tools in the Digital Age

Marketing communications has gone through significant changes during the last decades and new online tools have been leading this change for the last decade. Now, in the digital age, if wanting to be successful companies need to experiment new things and seize the opportunities online provides and adapt to the new environment. However, during this time the marketing communication mix and the meanings given to the various components of it have not changed dramatically, and personal selling, direct marketing, sales promotion, advertising and public relations activities are still regarded as important tools in the marketing communications mix. The purpose of this study was to examine business-to-business marketing communications and the tools used by companies in their marketing communications efforts in the digital age and in a global environment. The research questions dealt with the marketing communication tools and their roles as well as the role of online marketing communication and the way it has shaped the field of b2b marketing communications. In order to answer these questions, qualitative approach was chosen and the data was collected by theme interviews with six representatives of Finnish global companies from the b2b sector being interviewed. The theoretical framework covers the general field of b2b marketing communications and its main elements. The online environment as well as the concept of a global marketplace and integrated approach to marketing communication activities is also discussed. The theory was supported by the interviews regarding the activities and roles of the marketing communication tools and both theory as well as the interviews found personal selling to be a vital tool. However, the importance of online has grown and online marketing activities have risen right next to personal selling. The use of analytics and marketing automation was found to be of great interest in the interviews and they were seen as a growing domain in b2b marketing communications. The importance of targeted and personalised messages from relevant medias was a repeating theme as was the customer-centric approach in marketing communication activities. Also, offline and online tools and channels were seen as something that should be treated together as an entity rather than as separate activities. Relevant content created according to the needs of the customer with the gathered data from analytics were seen as the future of b2b marketing communications. Online has added its input to the more traditionally perceived tools and they are executed within the framework of the digital age. Nevertheless, even though online has increased its presence in the b2b marketing communications mix, the more traditionally perceived marketing communication tools, especially personal selling, have not lost their meaning or place in the b2b marketing communication mix.

Reinventing the third way : towards new forms of economic and democratic conduct

Avhandlingen studerar samspelet mellan det politiska och det ekonomiska systemet genom det föregående seklet, med speciellt fokus på den nyliberala omdaning som utspelats de senaste tre årtiondena. Med en liberaliserad ekonomi och en individualiserad människa måste också det politiska systemet utformas på ett annat sätt. Gradvisa förändringar har varit synliga, som den växande nätverksorganiseringen, dvs. att olika typer av utvecklingspolitik allt mer genomförs som ett samspel mellan samhällssektorerna, istället för att enbart utföras av den offentliga sektorn som tidigare. Genom fyra fallstudier i Österbotten demonstreras hur arenor för samverkan kan konstrueras i enlighet med vad den aktuella frågan kräver. Ett exempel är det innovationsnätverk som skapats i Karleby-Jakobstad-regionen, där offentliga och privata intressenter deltar, och som samtidigt bryter traditionella administrativa gränser. Ett annat mer negativt exempel är omstruktureringsprocessen i Kaskö-regionen eft er Metsä-Botnia-fabrikens nedläggning, där småkommunproblemet tillsammans med att den privata intressenten inte haft skyldighet att samverka lett till att en tillräckligt regionalt förankrad arena för en långsiktig utvecklingspolitik inte har kunnat skapas. Det här visar på trögheten i det finska systemet, där en stark enhetsstat och en splittrad kommunal nivå ur ett historiskt perspektiv hindrat flexibla anpassningar till samhällsförändringar. Avhandlingen visar att nätverksorganiseringen bör vara en integrerad del av de representativa strukturerna för att kunna påverka processernas utfall. Avhandlingen visar framförallt att deltagande och funktionellt definierade regionala och lokala arenor har stor potential, både ekonomiskt och demokratiskt. Det handlar om att skapa en kultur med aktiverade och engagerade medborgare, vilket står i kontrast till det allt mer passiverande representativa systemet. ---------------------------------------- Väitöskirja tutkii viime vuosisadan poliittisen ja taloudellisen järjestelmän vuorovaikutusta keskittyen erityisesti kolmen viimeisen vuosikymmenen uusliberaaliseen muutokseen. Talouden liberalisoituminen ja ihmisen individualisoituminen edellyttävät myös poliittisen järjestelmän mukautumista. Asteittaisia muutoksia on ollut havaittavissa, kuten kasvava verkosto-organisaatio, toisin sanoen eri alojen kehityspolitiikkaa toteutetaan yhä enemmän eri yhteiskuntasektoreiden vuorovaikutuksena, kun aikaisemmin ainoastaan julkinen sektori vastasi kehityspolitiikan toteuttamisesta. Pohjanmaan maakunnan neljän tapaustutkimuksen avulla osoitetaan, miten vuorovaikutusareena voidaan rakentaa kulloinkin ajankohtaisen asiakokonaisuuden ympärille. Tästä esimerkkinä on Kokkola-Pietarsaari –alueen innovaatioverkosto, johon osallistuvat sekä julkiset että yksityiset sidosryhmät ja joka samalla rikkoo perinteisiä hallinnollisia rajoja. Toinen, kielteisempi esimerkki on Kaskisten alueen rakennemu utosprosessi Metsä-Botnian tehtaan sulkemisen jälkeen. Siellä pienkuntaongelma yhdistettynä siihen, että yksityinen sidosryhmä ei ole ollut velvollinen tekemään yhteistyötä, on johtanut siihen, että ei ole kyetty luomaan alueen pitkäaikaiseen kehittämiseen sitoutunutta vuorovaikutusareenaa. Tämä osoittaa suomalaisen järjestelmän kankeuden, jossa historiallisesta näkökulmasta vahva yhtenäinen valtio ja hajanainen kuntataso estävät joustavan yhteiskuntamuutoksiin sopeutumisen. Väitöskirja osoittaa, että verkosto-organisaation on oltava yhteiskunnassa vaikuttaviin rakenteisiin integroitu osa, jotta se voi vaikuttaa prosessien tuloksiin. Väitöskirja osoittaa ennen kaikkea, että osallistuvilla ja toiminnallisesti määritellyillä alueellisilla ja paikallisilla areenoilla on suuri taloudellinen ja demokraattinen potentiaali. Passivoivan edustavan järjestelmän tilalle on luotava aktiivisten ja tavoitteisiin sitoutuneiden kansalaisten vuorovaikutusjärjestelmä.

Leptin levels in different forms of Chagas' disease

Leptin is produced primarily by adipocytes. Although originally associated with the central regulation of satiety and energy metabolism, increasing evidence indicates that leptin may be an important mediator in cardiovascular pathophysiology. The aim of the present study was to investigate plasma leptin levels in patient with Chagas' heart disease and their relation to different forms of the disease. We studied 52 chagasic patients and 30 controls matched for age and body mass index. All subjects underwent anthropometric, leptin and N-terminal pro-brain natriuretic peptide (NT-proBNP) measurements and were evaluated by echocardiography, 12-lead electrocardiogram (ECG), and chest X-ray. All patients had fasting blood samples taken between 8:00 and 9:00 am. Chagasic patients were divided into 3 groups: group I (indeterminate form, IF group) consisted of 24 subjects with 2 positive serologic reactions for Chagas' disease and no cardiac involvement as evaluated by chest X-rays, ECG and two-dimensional echocardiography; group II (showing ECG abnormalities and normal left ventricular systolic function, ECG group) consisted of 14 patients; group III consisted of 14 patients with congestive heart failure (CHF group) and left ventricular dysfunction. Serum leptin levels were significantly lower (P < 0.001) in the CHF group (1.4 ± 0.8 ng/mL) when compared to the IF group (5.3 ± 5.3 ng/mL), ECG group (9.7 ± 10.7 ng/mL), and control group (8.1 ± 7.8 ng/mL). NT-proBNP levels were significantly higher (P < 0.001) in the CHF group (831.8 ± 800.1 pg/mL) when compared to the IF group (53.2 ± 33.3 pg/mL), ECG group (83.3 ± 57.4 pg/mL), and control group (32 ± 22.7 pg/mL). Patients with Chagas' disease and an advanced stage of CHF have high levels of NT-ProBNP andlow plasma levels of leptin. One or more leptin-suppressing mechanisms may operate in chagasic patients.

Measuring Effectiveness of Marketing Message: The Role of Verbal, Visual and Brand Elements

The aim of this paper is to study the role of verbal, visual and brand elements while meas-uring effectiveness of marketing message. The thesis is written in the context of mobile gaming industry. The object of the study is marketing message. To achieve the aim, the main research question was formulated: How do the elements of marketing message, such as verbal, visual and brand, affect the consumer’s attitude toward the ad, emotional response and attention capture? The theory development chapter lays on three corner stones – analysis of previous litera-ture on marketing message and its elements, namely verbal, visual and brand; overview of literature on attitude formation and particularly attitude toward the ad. In addition, investiga-tion of key points of emotional response and attention capture literature finalizes the chap-ter. The empirical part consists of experiment, conducted with 27 participants. Experiment includes the self-report semantically anchored scale, measuring the attitude toward the ad, as well as autonomic measures – eye tracking (attention capture) and facial expressions (emotional response). The results of the experiment showed that the size of the brand element – the logo – has an effect on the attention capture and the overall attitude toward the ad. The bigger the logo, the more time people spend viewing it, and they realise the message is more educa-tional and factual. The measure related to the visual element – the visual complexity – in-creases the intensity of participant’s facial expression. While the measure of verbal ele-ment – the contrast between text and background colours – leads to a better attitude to-ward the ad. The higher the contrast between text and background, the more known the message appears to the viewer.

Integration of marketing research data in new product development. Case study: Food industry company

The aim of this master’s thesis is to provide a real life example of how marketing research data is used by different functions in the NPD process. In order to achieve this goal, a case study in a company was implemented where gathering, analysis, distribution and synthesis of marketing research data in NPD were studied. The main research question was formulated as follows: How is marketing research data integrated and used by different company functions in the NPD process? The theory part of the master’s thesis was focused on the discussion of the marketing function role in NPD, use of marketing research particularly in the food industry, as well as issues related to the marketing/R&D interface during the NPD process. The empirical part of the master’s thesis was based on qualitative explanatory case study research. Individual in-depth interviews with company representatives, company documents and online research were used for data collection and analyzed through triangulation method. The empirical findings advocate that the most important marketing data sources at the concept generation stage of NPD are: global trends monitoring, retailing audit and consumers insights. These data sets are crucial for establishing the potential of the product on the market and defining the desired features for the new product to be developed. The findings also suggest the example of successful crossfunctional communication during the NPD process with formal and informal communication patterns. General managerial recommendations are given on the integration in NPD of a strategy, process, continuous improvement, and motivated cross-functional product development teams.

Influence of levels and forms of selenium associated with levels of vitamins C and E on the performance, yield and composition of tilapia fillet

The objective of this study was to evaluate the influence of vitamin C (VC), vitamin E (VE), and two selenium sources on the performance, yield, and composition of Nile tilapia fillet. The experiment was conducted in a completely randomized design consisting of six treatments with the addition of 100, 200, and 400 mg kg-1 VC and VE and 0.1, 0.2, and 0.4 of two sources of selenium. Each treatment had five replicates of 30 fish each. The diet with 200 mg kg-1 VC and VE + 0.2 mg.k-1 organic selenium resulted in weight gain, length gain, and feed conversion ratio similar to that of the treatment with 400 mg kg-1 VC and VE + 0.4 mg kg-1 organic or inorganic selenium. The addition of organic selenium to the diet improved the weight gain and feed conversion ratio in comparison with the addition of inorganic selenium. The diet with 0.2 mg kg-1 organic selenium showed glutathione peroxidase level equal to the diet with 0.4 mg kg-1 of inorganic selenium. Carcass and fillet yields were not affected by treatments; however, there was treatment effect on the fillet's chemical composition.

Prospects of Marketing the Indigenous Ornamental Fishes of Kerala

In this study prospects of marketing the indigenous ornamental fishes of kerala, point out that the export market, consumer preferences in the domestic ornamental fishes, SWOT (strength weakness opportunities and threats) analysis etc. The study notes that the product indigenous ornamental fishes are mostely marketed by exporters and suppliers rather than the retail aquarium shopkeepers. The research findings on the attributes of indigenous ornamental fishes that matches customers preference in aquarium fish.SWOT analysis was carried out to classify the results of the study into strengths,weakness,opportunities and threats faced by the ornamental fish industry in kerala. The marketers in the study show less market perception compaired to the exporters of India. Rather than market survey, interest and experience and raw materials availability inspires them. The developments for large scale marketing have to be carried out, ensuring the sustainable exploitation of the wild fish population by adopting conservation measures such as breeding programmes, quota implementation, setting up of natural sanctuaries to protect the natural resource of ornamental fishes.

Effect of Different Forms of Poly o-Toluidine /Poly Vinyl Chloride Composites on Dielectric Propertiesin the Microwave Field

In this paper we report the preparation and dielectric properties of poly o-toluidine:poly vinyl chloride composites in pellet and film forms. The composites were prepared using ammonium persulfate initiator and HCl dopant. The characterization is done by TGA and DSC. The dielectric properties including dielectric loss, conductivity, dielectric constant, dielectric heating coefficient, absorption coefficient, and penetration depth were studied in the microwave field. An HP8510 vector network analyzer with rectangular cavity resonator was used for the study. Sbands (2-4 GHz), C band (5-8 GHz), and X band (8-12 GHz) frequencies were used in the microwave field. Comparisons between the pellet and film forms of composites were also included. The result shows that the dielectric properties in the microwave field are dependent on the frequency and on the method of preparation.
